feat: implement cli flag to fail flaky tests

docs/src/test-cli-js.md

@@ -81,6 +81,7 @@ Complete set of Playwright Test options is available in the [configuration file]
 | Non-option arguments | Each argument is treated as a regular expression matched against the full test file path. Only tests from the files matching the pattern will be executed. Special symbols like `$` or `*` should be escaped with `\`. In many shells/terminals you may need to quote the arguments. |
 | `-c <file>` or `--config <file>`| Configuration file. If not passed, defaults to `playwright.config.ts` or `playwright.config.js` in the current directory. |
 | `--debug`| Run tests with Playwright Inspector. Shortcut for `PWDEBUG=1` environment variable and `--timeout=0 --max-failures=1 --headed --workers=1` options.|
+| `--fail-on-flaky-tests` | Fails test runs that contain flaky tests. By default flaky tests count as successes. |
 | `--forbid-only` | Whether to disallow `test.only`. Useful on CI.|
 | `--global-timeout <number>` | Total timeout for the whole test run in milliseconds. By default, there is no global timeout. Learn more about [various timeouts](./test-timeouts.md).|
 | `-g <grep>` or `--grep <grep>` | Only run tests matching this regular expression. For example, this will run `'should add to cart'` when passed `-g "add to cart"`. The regular expression will be tested against the string that consists of the test file name, `test.describe` titles if any, test title and all test tags, separated by spaces, e.g. `my-test.spec.ts my-suite my-test @smoke`. The filter does not apply to the tests from dependency projects, i.e. Playwright will still run all tests from [project dependencies](./test-projects.md#dependencies). |
